Setting up Secondary DNS on same machine

[MarcoA]

Hi there,

I currently have all the domains on my PLESK machin using 3 nameservers:
- Primary: the DNS server on the PLESK machine itself
- Secondaries: outside this machine (no PLESK)

Unfortunately I'll have to give up on the machines that are the secondaries DNS servers and I want to use the same PLESK box for both primary and secondary DNS.

How can I achieve this? (I already have a similar setup on my cPanel machines)

Anyone? I really need to setup this ASAP!
